Affecting factors of CO2 evolution from biodegradation of agricultural organic wastes

Abstract

Abstract: On the basis of a preliminary orthogonal design experiment,from which,the primary parameters suitable for the CO₂ evolution from bio-degradation of agricultural organic wastes had been obtained,four single factor experiments were installed in greenhouse to seek the optimal parameters for the CO₂ evolution.The results showed that the optimal parameters for the CO₂ evolution from the bio-degradation of rice straw-pig manure mixture were 50 ℃,70% water content and initial pH 6.0～7.0.For fermentation,the optimal initial C/N ratio of substrate for cumulative CO₂ evolution was 40/1,but 30/1 was better for compost.The effect of the four parameters on CO₂ evolution was in the order of C/N ratio and water content>temperature>pH.
